* $Logfile: /Freespace2/code/Graphics/GrD3D.cpp $
* $Revision: 2.5 $
* $Date: 2003-03-02 05:43:48 $
* $Author: penguin $
*
* Code for our Direct3D renderer
*
* $Log: not supported by cvs2svn $
* Revision 2.4 2003/01/14 05:53:58 Goober5000
* commented out some mprintfs that were clogging up the debug spew
* --Goober5000
*
* Revision 2.3 2002/10/05 16:46:09 randomtiger
* Added us fs2_open people to the credits. Worth looking at just for that.
* Added timer bar code, by default its not compiled in.
* Use TIMEBAR_ACTIVE in project and dependancy code settings to activate.
* Added the new timebar files with the new code.
*
* Revision 2.2 2002/08/01 01:41:05 penguin
* The big include file move
*
* Revision 2.1 2002/07/30 14:29:15 unknownplayer
*
* Started work on DX8.1 implementation. Updated the project files to encompass
* the new files. Disable the compiler tag to use old DX code (THERE IS NO
* NEW CODE YET!)
*
* Revision 2.0 2002/06/03 04:02:22 penguin

* 29 7/27/99 3:09p Dave
* Made g400 work. Whee.
*
* 28 7/24/99 4:19p Dave

* better. Made model code use zbuffer more intelligently.
*
* 27 7/16/99 1:49p Dave
* 8 bit aabitmaps. yay.
*
* 26 7/14/99 9:42a Dave

*
* 109 6/13/98 3:18p Hoffoss
* NOX()ed out a bunch of strings that shouldn't be translated.
*
* 108 5/24/98 9:41p John
* changed allender's previous fix to actually not draw the lines on
* NDEBUG.
*
* 107 5/24/98 9:16p Allender
* put in previously non-NDEBUG code to draw bogus cursor when Gr_cursor
* wasn't defined. Caused d3d to crash before playing movies
*
* 106 5/22/98 10:29p John
* fixed some mode switching and line offset detection bugs.
*
* 105 5/22/98 1:11p John
